An Integrated World Modeling Theory (IWMT) of consciousness: Combining Integrated Information and Global Neuronal Workspace Theories with the Free Energy Principle and Active Inference Framework; towards solving the Hard problem and characterizing agentic causation

Adam Safron preprint

The Free Energy Principle and Active Inference Framework (FEP-AI) begins with the understanding that persisting systems must regulate environmental exchanges and prevent entropic accumulation. In FEP-AI, minds and brains are predictive controllers for autonomous systems, where action-driven perception is realized as probabilistic inference. Integrated Information Theory (IIT) begins with...

It’s Movement all the Way Down: Broken Rhythms and Embodied Selfhood in Depersonalization

Veronika Alekseeva, Anna Ciaunica preprint

From the moment we are born, and even before, in the womb, and until our last breath, our bodies move all the time. Adaptive behaviors necessarily depend not only on successful integration of multisensory bodily signals but also on how we move our body in the world. This paper considers the notion of embodied selfhood through the perspective of dynamic and rhythmic coupling between bodily...

New insights into the clinical and nonclinical effects of psychedelic substances: an integrative review

Matthias Forstmann, Christina Sagioglou preprint

After decades of stagnancy, research on psychedelic substances (such as LSD, psilocybin or DMT) has experienced a renaissance over the last 10 years, with various major research programs being conducted across Europe and the United States. This research primarily investigates the potential of psychedelics in the treatment of mental health disorders, their short and long term effects on...

Abuse of Dextromethorphan, Carbamazepine, and Naphazoline

Ahmad R. Alsayed preprint

The misuse and abuse of over-the-counter (OTC) and prescription medications pose significant public health concerns. Among these, Dextromethorphan (DXM), Carbamazepine, and Naphazoline have gained attention due to their increasing non-medical use. DXM, a common cough suppressant, is abused for its dissociative and euphoric effects, leading to dependency and severe health risks. Carbamazepine,...

Individual differences in the pharmacokinetic profiling of Δ9-THC may be associated with differential motivational effects of Δ9-THC on cognitive performance

Teneisha M. Myers, Noah C. Neverette, Aaron S. Devanathan et al. preprint

Abstract Rationale Cannabis is the most widely used illicit substance in the United States, and its use is increasing with the recent push for legalization and decriminalization, as well as the growing use for medicinal purposes. While cannabis can have positive effects in some individuals, there are potential negative consequences including dependence, psychosis, and cognitive impairments. The...

Influence of solvent, sex, and age on pharmacokinetic and acute behavioral effects of vaporized cannabis extract in mice

Sara R Westbrook, Allison L Jensen, Vanessa Copeland-Solorzano et al. preprint

Abstract The legalization of cannabis in several states across the US has increased the need to better understand its effects on the body, brain, and behavior, particularly in different populations. Rodent models are particularly valuable in this respect because they provide precise control over external variables. Previous rodent studies have found age and sex differences in response to...

Cannabis induced psychosis: A comparative study between cannabis use disorder and cocaine use disorder

Maurizio Coppola, Raffaella Mondola preprint

Psychosis can be defined as a combination of psychopathological symptoms including delusions and/or hallucinations without insight. Psychotic disorders may configure a primary psychiatric illness or represent the result of a functional/structural brain damage induced by substance use, neurological diseases or other medical conditions. They are multifactorial disorders in which genetic,...

Insular Cortical Thinning and Altered Structural Connectivity in Chronic Cannabis Users: A High-Resolution Morphometry and Diffusion Tractography Study

Fouad Meraji Far, Hamid Reza Banafshe, Amir Ghaderi et al. preprint

Abstract Background The insula, a central hub of the salience network, is implicated in craving and loss of control in addiction. Despite its relevance, the structural morphometric and white matter connectivity correlates of chronic cannabis use remain inconsistent across studies. Methods Twenty-six all-male participants (13 chronic cannabis users, 13 controls) underwent a 3.0 Tesla MRI....

Development of Bioisosteric Iboga -alkaloids as Antinociceptive and Anxiolytic Agents with Neuroprotective Effects

Abhishek Gupta, Tuhin Bhattacharya, Subhamoy Pratihar et al. preprint

Abstract The clinical importance of iboga alkaloids lies in their efficacy in reversing drug addiction and modulating drug tolerance. However, due to safety concerns, their use is restricted to appropriate medical supervision. These alkaloids often cause severe hallucinogenic effects due to differential binding to various brain receptors and cardiotoxicity by blocking the human...

Sensing minimal self in a sentence that involves the speaker

Ryoko Uno, Shu Imaizumi preprint

The contribution of language to the narrative self is well-known, but does language play a role in creating the sense of minimal self? In this paper, we investigated whether variations in sentence structure affected the speaker's sense of minimal self. We examined whether expressing the first-person subject's actions and perceptions in sentences influenced the speaker's sense of agency and...
